Definitions
- the present invention relates to a method for forming a composite elastic material suitable for use in disposable absorbent articles such as disposable diapers, incontinence briefs, training pants, feminine hygiene garments, and the like.
- composite elastic material refers to a multilayer or multicomponent material adapted to stretch and recover and which has at least one elastic member, layer or component, such as an elastic scrim, joined to another member, layer or component such as a thermoplastic film.
- absorbent articles have a tendency to sag or gap away from and to slide/slip down on the body of the wearer during wear.
- This sagging/gapping and sliding/slipping is caused by the relative motions of the wearer as the wearer breathes, moves, and changes positions by the downward forces generated when the absorbent article is loaded with body exudates, and by the deformation of the materials of the absorbent article itself when subjected to such wearer's motions.
- This sagging/gapping and sliding/slipping of the absorbent article can lead to premature leakage and poor fit of the absorbent article about the wearer in the waist regions and the leg regions of the absorbent article.
- the present invention provides a method for forming a composite elastic material.
- a thermoplastic film is extruded from an extruder.
- the extruded thermoplastic film is then fed while still in a molten condition onto a rotating forming structure exhibiting a multiplicity of apertures therein.
- the thermoplastic film has a surface facing the forming structure and another surface facing away from the forming structure.
- a pneumatic vacuum is applied to the thermoplastic film to produce apertures in the thermoplastic film.
- An elastic member comprising at least one elastic strand is placed against a surface of the thermoplastic film while the thermoplastic film is still in a molten condition.
- the elastic member is preferably placed against the surface of the thermoplastic film facing away from the forming structure.
- the elastic member bonds to the apertured molten film to form a breathable composite elastic material.
- the composite comprising the molten film and the elastic member is fed through a pressure nip comprising a pair of opposed pressure applicators.
- the elastic member preferably comprises a plurality of longitudinal strands and a plurality of transverse strands interconnected to one another.
- all of the longitudinal and transverse strands are comprised of an elastic material.
- only the longitudinal strands or only the transverse strands are comprised of an elastic material depending on the desired direction of stretch of the composite elastic material.
- the other strands which are not elastic are preferably comprised of a thermoplastic material.
- FIG. 1 is a plan view of an absorbent article comprising the composite elastic material formed according to the method of the present invention in the elasticized waistband and in the elasticized side panels;
- FIG. 2 is a simplified side elevation view showing a method for forming the composite elastic material of the present invention
- FIG. 3 is an enlarged fragmentary perspective illustration of a forming structure of the present invention.
- FIG. 4 is an enlarged fragmentary perspective illustration of a preferred elastic member of the present invention.
- FIG. 5 is an enlarged fragmentary perspective illustration of a composite elastic material formed according to the method of the present invention.
- absorbent article refers to devices which absorb and contain body exudates, and, more specifically, refers to devices which are placed against the skin of the wearer to absorb and contain the various exudates discharged from the body.
- dispenser is used herein to describe absorbent articles which are not intended to be laundered or otherwise restored or reused as an absorbent article after a single use, (i.e., they are intended to be discarded and preferably, recycled, composted or otherwise disposed of in an environmentally compatible manner).
- a “unitary” absorbent article refers to an absorbent article which is formed of separate parts united together to form a coordinated entity so that they do not require separate manipulative parts like a separate holder and liner.
- a preferred embodiment of a unitary absorbent article comprising an elasticized waistband and elasticized side panels each comprising the composite elastic material formed by the method of the present invention is the disposable absorbent article, disposable diaper 20, shown in FIG. 1.
- the term "diaper” refers to an absorbent article generally worn by infants and incontinent persons that is generally worn about the lower torso of the wearer. It should be understood, however, that the present invention is also applicable to other absorbent articles such as incontinence briefs, diaper holders, feminine hygiene garments, training pants, and the like.
- an absorbent article such as diaper 20 generally comprises a top sheet 22, a backsheet 24 joined to the topsheet 22, and an absorbent core 26 positioned between the topsheet 22 and the backsheet 24.
- the diaper 20 preferably further comprises elasticized leg cuffs 28, elasticized side panels 30, an elasticized waistband 32 and a fastening system 34.
- the diaper 20 is shown in FIG. 1 to have an outer surface 42 (facing the viewer in FIG. 1), an inner surface 44 opposed to the outer surface 42, a front waist region 36, a rear waist region 38 opposed to the front waist region 36, a crotch region 39 positioned between the front waist region 36 and the rear waist region 38, and a periphery which is defined by the outer perimeter or edges of the diaper in which the longitudinal edges are designated 46 and the end edges are designated 48.
- the inner surface 44 of the diaper 20 comprises that portion of the diaper 20 which is positioned adjacent to the wearer's body during use (i.e., the inner surface 44 generally is formed by at least a portion of the topsheet 22 and other components joined to the topsheet 22).
- the outer surface 42 comprises that portion of the diaper 20 which is positioned away from the wearer's body (i.e., the outer surface 42 is generally formed by at least a portion of the backsheet 24 and other components joined to the backsheet 24).
- the term "joined” encompasses configurations whereby an element is directly secured to the other element by affixing the element directly to the other element in configurations whereby the element is indirectly secured to the other element by affixing the element to intermediate member(s) which in tum are affixed to the other element.
- FIG. 1 shows a preferred embodiment of the diaper 20 in which the topsheet 22 and the backsheet 24 have length and width dimensions generally larger than those of the absorbent core 26. The topsheet 22 and the backsheet 24 extend beyond the edges of the absorbent core 26 to thereby form the periphery of the diaper 20.
- the absorbent core 26 may be any absorbent means which is generally compressible, conformable, non-irritating to the wearer's skin, and capable of absorbing and containing liquids such as urine and other body exudates. As shown in FIG. 1, the absorbent core 26 has a garment surface, a body surface, side edges, and waist edges.
- the absorbent core may be manufactured in a wide variety of sizes and shapes and form a wide variety of liquid-absorbent materials commonly used in disposable diapers and other absorbent articles such as comminuted wood pulp, which is generally referred to as airfelt.
- absorbent materials include creped cellulose wadding; meltblown polymers including coform; chemically stiffened, modified, or cross-linked cellulosic fibers; tissue including tissue wraps and tissue laminates; absorbent foams; absorbent sponges; superabsorbent polymers; absorbent gelling material; or any equivalent material or combinations of materials.
- the configuration and construction of the absorbent core may also be varied (e.g., the absorbent core may have varying caliper zones, a hydrophilic gradient, a superabsorbent gradient, or a lower average density and lower average basis weight acquisition zones; or may comprise one or more layers or substrates).
- the total absorbent capacity of the absorbent core should, however, be compatible with the design loading and the intended use of the diaper 20. Further, the size and absorbent capacity of the absorbent core may be varied to accommodate wearers ranging from infants through adults.
- the backsheet 24 is preferably impervious to liquids (e.g., urine) and is preferably manufactured from a flexible material.
- the term "flexible” refers to materials which are compliant and will readily conform to the general shape and contours of the human body.

- the forming drum 118 preferably includes an internally located vacuum chamber 120 which is preferably stationary relative to the moving forming structure 115.
- Forming structure 115 includes a plurality of apertures 116.
- the forming structure 115 exhibits a fiber-like cross-section of a type generally disclosed in commonly assigned U.S. Pat. No. 4,342,314 issued to Radel et al. on Aug. 3, 1982, which patent is hereby incorporated herein by reference.
- the forming structure 115 may have various aperture sizes, aperture shapes, and aperture densities.
- the aperture spacing may be in a regular pattern or it may vary randomly, as desired. Examples of other suitable forming structures are disclosed in commonly assigned U.S. Pat. No. 4,609,518 issued to Curro et al. on Sep. 2, 1986, which patent is hereby incorporated herein by reference.
- thermoplastic film 130 is fed onto the forming drum 118 about which forming structure 115 continuously rotates, one surface of the thermoplastic film faces the forming structure 115 and directly contacts the forming structure 115 while the opposed surface of the thermoplastic film faces away from the forming structure 115.
- the vacuum chamber 120 subjects the thermoplastic 130 film to a pneumatic vacuum. The pneumatic vacuum sucks portions of the thermoplastic film 130 into the apertures 116 of the forming structure 115 thereby forming apertures in the thermoplastic film.
- an elastic member 100 comprising at least one elastic strand, preferably a plurality of elastic strands, is fed from a supply roll 102 and placed against the surface of the still molten thermoplastic film 130.
- the elastic member 100 is placed against a surface of the molten film after the molten film has been apertured and removed from the forming structure 115.
- the elastic member 100 may be placed against the molten film while the molten film is still residing on forming structure 115.
- the elastic member 100 bonds to the molten apertured thermoplastic film to form a breathable composite elastic member 160.
- the composite 160 is fed through a pressure nip 169 comprising opposed pressure applicators 170 and 171.
- the composite elastic material 160 is then fed from pressure nip 169 to wind up roll 172.
- the elastic scrim 100 comprises a plurality of elastic strands 105 extending in a first or longitudinal direction and a plurality of elastic strands 106 extending in a second or transverse direction perpendicular to the first direction.
- the longitudinal strands 105 and the transverse strands 106 are interconnected to one another.
- the elastic scrim 100 has a plurality of openings or apertures 107 distributed therein to produce a netlike construction.
- the elastic strands 105 and 106 are shown in FIG. 4 to be oriented to produce openings 107 having a generally square configuration.
- elastic strands 105 and 106 may be arranged to produce openings of other configurations such as rectangular, diamond, etc.
- the elastic scrim 100 of the present invention need not have the symmetrical, regular array of apertures of a reticulated member, but may merely include a plurality of interconnected elastic elements defining apertures therebetween.
- the number of openings 107 may vary from 2 to 100 openings per linear inch in both the longitudinal and transverse direction of the elastic member 100.
- the elastic strands 105 and 106 may be of different widths in the longitudinal or transverse direction, and the spacing between the elements may vary from the transverse to the longitudinal direction.
- the thickness of the elastic scrim 100 is preferably from about 1 mil to about 50 mils and more preferably from about 5 mils to about 20 mils.
- suitable materials for use as the elastic strands 105 and 106 include but are not limited to elastomeric foams, "live" synthetic or natural rubber, and lycra. In some embodiments it may be necessary for both elastic strands 105 and 106 to be elastic. This is true where it is desirable to provide stretch in multiple directions. However, in other embodiments, it may be necessary for only one of the strands, either one of strands 105 or 106 to be elastic. This is true where it is desirable to provide stretch in only one direction. In those situations where it is desirable to provide stretch in only one direction, at least one of the elastic strands, for example elastic strand 105, need be elastic.
- the other elastic strand for example elastic strand 106, may be made from a wide variety of other materials.
- suitable materials for use as the non-elastic strands 106 include but are not limited to thermoplastic materials such as polyethylene, polypropylene, and polyester and the like.
- the breathable composite elastic material 160 comprises the elastic member 100 comprising interconnected elastic strands 105 and 106 bonded to apertured thermoplastic film 130.
- Apertured film 130 comprises a plurality of apertures 133 generally corresponding to apertures 116 in forming structure 115, as shown in FIG. 3.
- the apertures 133 in the apertured film 130 are preferably smaller in size than the openings 107 of the elastic member 100. However, the apertures 133 may be the same size as the openings 107 or larger than the openings 107 in the elastic member 100.
- the apertures 133 in the composite elastic material 160 allow the composite to be breathable permitting the passage and air and vapor.
- the composite elastic material is both as elastic, breathable, and relatively low cost compared to traditional elastic materials.
- An alternative elastic member comprises a single elastic strand which is oscillated in a back and forth motion as it is fed from a supply source.
- multiple elastic strands may be fed in an oscillating manner and placed against a face of the molten apertured thermoplastic film.
- a plurality of elastic strands are fed in the machine direction and placed against a face of the molten apertured thermoplastic film.
- the elastic strands are not oscillated in a back and forth motion. Any number of elastics strands may be used.
- thermoplastic film may be apertured by impinging a jet of high pressure liquid on the exposed surface of the thermoplastic film while the film is supported on the forming structure.
- a jet of high pressure liquid is described in U.S. Pat. No. 4,629,643 issued to Curro et al. on Dec. 16, 1986 and is hereby incorporated herein by reference.
